O-Ring Seals for all the OEM Fuel lines to the fuel bowl and the fuel lines connecting to the heads. 1999-2003 7.3L Powerstroke Only.

If your removing your fuel bowl to install a new high pressure oil pump, you may want to replace these seals to prevent leakage after re-install. If you have an aftermarket fuel system, you may not need these. However, if you do need the return line seal (top driver's side of fuel bowl), you will still need to purchase the complete kit as this seal is not available separately.
